OF ONE-HALF TO JOHN M.

DRIVER, OE SAME PLACE.

SPRING-MOTOR.

SPECIFICATION forming part of Letters Patent No. 298,388. dated May 13, 1884.

Application filed March 13, 1884. (No model.)

To all whom it may concern..-

Be it known that I, ALEXANDER KANTHACK, of the city and county of Philadelphia, State of Pennsylvania, a subject of the King of Prussia, having resided one year last past in the United States, and made oath of intention to become a citizen thereof, have invented a new and useful Improvement in Spring-Motors, which improvement is fully set forth in the following speeification and accompanying drawings, in which Figure l is a front view, partly sectional, of aspring-motorembodyingmyinvention. Fig. 2 is a vertical section in lineww, Fig. 1. Fig. 3 is a vertical section in line y y, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists of a motor having a multiple spring, an unbroken shaft, and a drum, both being common to all of the springs.

It also consists of gearing for communicating the power of the spring to a shaft, as will be hereinafter set forth.

Referring to the drawings, A represents a shaft, which is mounted on a frame, B.

(J represents a drum, which has at opposite ends a hollow journal, a, and a sleeve, to, the

shaft passing freely through the journal to and through the hub b of a gear-wheel, D, said hub being encircled by the sleeve a and connected therewith by means of a screw, 0, said wheel D being mounted by its huh I) on the portion B of the frame B.

E represents a series of coiled springs within the drum, one end of each being connected with the shaft A and the other end with the drum, the several springs being arranged parallel, side by side.

F represents a train of gearing, consisting of the pinion d, spur-wheel e, pinion f, spurwheel 9, pinion h, spur-wheel k, and pinion m, the shafts of the several parts being mounted on the frame. The pinion d meshes with the wheel D, and the pinion m is keyed or otherwise secured to a shaft, G, which isproperly mounted on the frame, and is formed with a crank or carries a crank-wheel or band-wheel, as desired, whereby the power of the motor may be transmitted to the place of service.

The operation is as follows: The shaft A is rotated by the crank-handle, the drum being held by a brake suitably applied to said drum or to the shaft G, and the springs are wound on the shaft. The shaft is now prevented from rotation in reverse order by means of a pawl, a, hung from the frame, and engaging with a ratchet, p, on the shaft A. When the brake of the motor is released, the springs are uncontrolled and immediately exert their power, causing the drum 0 to rotate, and thus transmit said power through the sleeve a and hub 11 of the wheel D to the latter wheel, and consequently to the train F, whereby the shaft G is rotated, the power whereof being communicated elsewhere, such as the driving-shaft of a sewingmachine, &c. The part B of the frame constitutes a box to inclose the gearing D F. The multiple spring employed is of great power, the several springs constituting the same being of small diameters, obviating the employment of a spring and drum of large diameters and great expense thereof, and permitting the use of a drum comparatively narrow, the length of the same being unobjectionable.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. A spring-motor having a multiple spring formed of a series of parallel springs, and an unbroken shaft, and a drum with which the springs are connected, said shaft and drum being common to all of the springs, substantially as and for the purpose set forth.

2. A winding-shaft and a spring connected v therewith, in combination wit-h a drum'inclosing a spring and connected therewith, a hollow journal and sleeve on opposite ends of the drum, a gearwvheel with a hub which freely encircles the shaft and is encircled by the sleeve of the drum, and a power-transmitting shaft and intermediate gearing, substantially as and for the purpose set forth.

3. A multiple spring, in combination with an inclosing-drum, a winding-shaft, a hollow journal and sleeve on opposite ends of said drum, a gear-wheel having a hub which encircles said shaftand is fixed to said sleeve, a train of gearing, and a power-transmitting shaft, substantially as and for the purpose set 1 0 forth.
